Answer:

A. )3(-3) - 2 = -11

B.) 3(1) - 2 = 1

C.) 3(5) - 2 = 13

Y = -11
Y = 1
Y = 13

Domain: -3, 1, 5

Range: -11, 1, 15

Input: -3, 1, 5

Output: -11, 1, 13

Function: Yes

Linear: Yes

{ (-3, -11) (1, 1) (5, 13) }

Step-by-step explanation:

A.)

3x - 2
3(-3) - 2 [3 x -3 = -9]
-9 -2 = -11

B.)

3(1) - 2 [3 x 1 = 3 Duh]
3 - 2 = 1

C.)

3(5) - 2 [3x5 = 15]

2. 15 - 2 = 13

Oint C is on line segment BD‾\overline{BD} BD . Given BD=5x,BD=5x, BD=5x, BC=4x,BC=4x, BC=4x, and CD=4,CD=4, CD=4, determine the

Gennadij [26K]

Answer:

Therefore the required value of $\overline{BD}$ is 20 units.

Step-by-step explanation:

Line Segment: Line segment is a portion of a line whose has two end points.

Given that point C is on the line segment $\overline{BD}$ .

$\overline{BD}$ = 5x , $\overline{BC}$ = 4x and $\overline{CD}$ = 4

C is the point of the line segment of $\overline{BD}$ .

So we can write

$\overline {BD}= \overline{BC}+\overline{CD}$

Putting the values of $\overline{BD}$ , $\overline{BC}$ and $\overline{CD}$

5x=4x+ 4

⇒5x-4x= 4

⇒x=4

So we get the value of x.

To get the value of $\overline{BD}$ , we need to put the value of x in the value of $\overline{BD}$ .

Therefore,

$\overline{BD}$ = 5×4

=20

Therefore the required value of $\overline{BD}$ is 20 units.

Triangle QRS is reflected over y = 2. What are the coordinates of Q'?

Levart [38]

Answer:

(1,6)

Step-by-step explanation:

In order to reflect a point over a horizontal line, you need to count how many units it takes to reach that line (going vertically). Once you have that number, count that many units starting from that point on the line (again, going vertically), then that is your reflected point.

Counting from point Q to the line y = 2, it takes 4 units. So starting from that point on the line where I left off, I would count another 4 units, taking me to (1,6). The picture below explains it better visually.
